Koyorad Radiator Cap 1.3 Bar - Red

Extract every ounce of cooling efficiency from Koyorad All Aluminum Performance Radiators with a genuine Koyorad Radiator Cap! This Koyorad Radiator Cap withstands an increased valve pressure rating of 1.3kgf/cm2 (1.3 bar) (18.9 psi) (130 kPa) which increases the boiling point of water and relieves high performance engines of excessive heat. A genuine Koyorad Radiator Cap is recommended for use with every Koyorad All Aluminum Performance Radiator (when applicable). This Koyorad Radiator Cap is manufactured in Japan from high quality components to ensure longevity and performance from your Koyorad Racing radiator.

Why is increased Pressure Better ?

It’s simple. When water is pressurised, its natural boiling point is increased. Most modern vehicles are equipped with a 0.9 Bar pressure cap. Koyorad’s Radiator Cap is rated at 1.3 Bar which increases the boiling temperature of your coolant. By increasing the boiling point of water, an engine's cooling system will have the added heat capacity, maximizing performance under ever-changing racing conditions.
